Abstract

The use of biolubricant must be encouraged to reduce environmental pollution from non-biodegradable lubricants by utilizing crude palm oil. This study aims to synthesize epoxide compounds from crude palm oil (CPO) as intermediate compounds to produce Biolubricant and determine the kinetic reaction and the enthalpy of the epoxide reaction. The process of synthesizing epoxide was carried out in a stirred reactor. The epoxidation reaction occurred at 60, 70, and 80 °C for 30 – 180 min with 30 min intervals using 1, 2, and 3% H2SO4 as catalysts. The highest conversion was obtained at a reaction temperature of 70 °C at 90 min using 2% H2SO4 of 87.59%. The characteristics of the epoxide compound produced have a density of 0.951 g/cm3, a kinematic viscosity of 44.388 CSt, an acid number of 4.32 mg NaOH/g oil, and oxirane number of 5.731 g/cm3. The reaction kinetic constant and enthalpy were 0.0104 mol/mL min and 10494.762 J/mol. The synthesized epoxide from crude palm oil was proven to be a suitable intermediate compound for biolubricant production.

Abstract

This paper analyzes several aspects (technical, marketing, economic, social, and financial) of canned smoked fish (Pangasius) as a micro-industry in South Sumatra Province, Indonesia. This article adopts mix-methods. A quantitative method is used to explain technical, marketing, economic, and financial aspects, while the social aspect is explained using a qualitative method. The author collects the Pangasius species sample from nine districts in South Sumatra Province for the technical aspect. This sample transformed into canned smoked fish using several steps: preparation, making and cooking, filling process, exhausting, sealing sterilization, and cooling process. The author also collects secondary data and interviews several key informants to analyze the non-technical aspect of the canned smoked fish industry. A canned smoked fish (Pangasius) has excellent potential to develop as a micro-enterprise in South Sumatra, Indonesia. In the long-term, it could be an instrument for the local government to increase citizens' well-being based on local resources and penetrate the ASEAN free trade area. In a short time, it could be an instrument for the local government to manage the economic effect of COVID-19 in South Sumatera, Indonesia. This study could be a baseline for the government to create a policy for developing the smoked fish industry. The result of this study could be a second opinion in planning capital investment within the smoked fish industry at the SSP for the investor and the entrepreneur.

Abstract

The clean water treatment process changes the physical, chemical, and biological properties of water so that it meets the requirements for use as drinking water or daily needs. The purpose of this research is to analyze the performance of ceramic membranes in processing water from the Kelekar River into clean water using an environmentally friendly microfiltration–adsorption–ceramic membrane integrated process. The research was carried out from January to April 2022 at the Chemical Engineering Laboratory of the Sriwijaya Polytechnic. The sampling location for this research is Kelekar River, Karang Raja Village, East Prabumulih. The main tools and materials are a series of water filters (microfiltration–adsorption–ceramic membrane) and river water. The analysis results show that a series of microfiltration-adsorption-ceramic membrane integrated process water treatment equipment can be used to treat river water into clean water. Based on the analysis of river water quality parameters, such as BOD5, iron (Fe), manganese (Mn), nitrate (NO3-), ammonia (NH3-N), and total coliform bacteria after water treatment were within environmental quality standards. Meanwhile, COD and nitrite (NO2-) were still not meeting the environmental quality standards set by Government Regulation of Republic Indonesia No. 22 of 2021 concerning the implementation of environmental protection and management.

Abstract

Adiwiyata School program is unable directly build the student’s environmental care character. Therefore, it is necessary to evaluate the students’ environmental care character at schools that won the Adiwiyata Award. This study aims to evaluate the environmental care character of students at Adiwiyata School. This study used a mixed-method, which combines quantitative and qualitative descriptive methods. The research sample was taken using the purposive sampling technique where the researcher took 110 students as the research sample. There are 3 (three) indicators used to evaluate students' environmental care character. The first indicator is the environmental cleanliness concern which showed 89.88% of students gave a positive value response. The second indicator is the knowledge of waste management which showed 90.07% of students gave a positive score response, and the last indicator is the knowledge about reforestation and natural resource management which showed 82.62% of students gave a positive score response. Based on the three indicators used, the overall response was a positive value of 75%. In accordance, the results of the study show that the average value of positive responses was 88.08%. Thus, it can be said that the environmental care character of students at SMPN 19 Palembang is in the very good category.

Abstract

Biochemistry Laboratory and Medicinal Chemistry as supporting facilities for practicum and research results in wastewater, which contains organic matter and suspended solids, such as TDS, Fe, Oil and Greases. If wastewater discarded directly to the drainage without passing sewage treatment system, then it potentially pollutes the environment and endangers the lives of living creatures. The purpose of this research is to evaluate the effectivity of the filtration system using ceramic membrane filtration technology to reduce the amount of TDS, Fe, Oil and Greases on laboratory’s wastewater. The filtration process is using ceramic membrane made of clay, activated carbon from lignite, and Fe powder. Pretreatment is done with the neutralization using NaOH 5N and coagulation using aluminum sulfate 400 mg/L. Variable in this research is the operating time of 5 and 20 minutes with operating pressure 1 kg/cm2. The result of this research shows that after 20 minutes operating, the reduction percentage of TDS, Fe, Oil and Greases after the process using ceramic membrane filtration technology were 0.97; 96.01; and 91.03 %, respectively. As the conclusion, the ceramic membrane is able to reduce the parameter of wastewater optimally. Keywords: ceramic membrane, coagulation, laboratory wastewater, lignite coal

Abstract

Buruknya kualitas air Sungai Betutu yang mengelilingi Pondok Pesantren Kiai Marogan Palembang serta minimnya pengetahuan tentang cara mendapatkan air bersih dan air minum menyebabkan pihak pesantren kesulitan mendapatkan air bersih dan air minum untuk memenuhi kebutuhan sehari-hari. Oleh karena itu, kegiatan ini bertujuan untuk membuat suatu teknologi terintegrasi nanofiltrasi-reverse osmosis guna memenuhi kebutuhan air bersih dan air minum para santri dan staff pengajar di Pondok Pesantren Kiai Marogan yang sesuai standar baku mutu lingkungannya. Metode pelaksanaan kegiatan pengabdian diawali dengan tahap persiapan, meliputi focus group discussion, survey lapangan, dan pengambilan sampel Sungai Betutu untuk mengetahui kualitas airnya. Setelah itu dilakukan tahap pengujian alat, tahap sosialisasi dan pelatihan, dimana pada tahap ini dilakukan penyuluhan tentang pentingnya air bersih dan bagaimana cara mendapatkannya serta pelatihan cara pengoperasian dan merawat alat yang diberikan. Tahap akhir adalah monitoring dan evaluasi yang dilakukan secara berkala terhadap kinerja alat serta mencari solusi untuk memecahkan masalah yang timbul selama proses teknologi ini digunakan. Dengan bertambahnya pengetahuan tentang pentingnya air bersih dan bagaimana cara mendapatkannya, teknologi ini dapat digunakan secara berkelanjutan dan pada akhirnya dapat meningkatkan kualitas hidup para santri dan staff pengajar di Pondok Pesantren Kiai Marogan. Produk air bersih dan air minum yang dihasilkan menunjukkan bahwa teknologi terintegrasi nanofiltrasi-reverse osmosis ini mampu meningkatkan pH dan mampu menurunkan kandungan TDS, Kekeruhan, Fe, Mn, NO2 dan koliform hingga memenuhi standar yang diatur pada Permenkes RI No. 32 Tahun 2017 untuk air bersih dan Permenkes RI No. 492 Tahun 2010 untuk air minum.
